Printed Protractor on Pasteboard
A protractor is a half circle divided into 180 degrees. Drawn in millimetres on an A4 page with an 80 mm radius, every degree mark is about 1.4 mm apart, enough to read to a degree. Printed at actual size and glued to stiff pasteboard, it measures as well as a shop one for paper and wood work. A 100 mm check line on the sheet catches a printer that shrinks the page.
